Abstract: A motor synchronization control strategy based on fuzzy PID algorithm was proposed to solve the problem of unsynchronized track under tail offset load. Firstly, the hydraulic simulation of the self-moving tail was carried out by AMESim through the mathematical model of the track force. Then, taking the multi-way valve as the controlled object, the motor angular displacement as the control variable, and the valve opening as the controlled variable, the fuzzy PID control model was established by MATLAB / Simulink, and the AMESim / MATLAB co-simulation model was established. Finally, by adjusting the current signal of the multi-way valve, the opening of the multi-way valve was changed, and the synchronization of the left and right motors was realized. The co-simulation results show that the fuzzy PID control strategy can realize the synchronization of the left and right motors within 3 s and overcome the interference within 1 s. The results show that the adjustment time and overshoot of the left motor speed are respectively reduced by 1.97 s and 35.53%. The fuzzy PID algorithm not only improves the anti-interference ability, but also makes the system obtain better dynamic response performance, which provides a certain technical reference for the track deviation prevention in the later underground coal mining.
